SIX3439K-TP

Overview

The SIX3439K-TP is a dual N-channel and P-channel MOSFET in a SOT-563 package. The N-channel device features a drain-source voltage of 20 V, continuous drain current of 0.75 A, and on-resistance of 0.38 Ω at VGS=4.5V. The P-channel device has a drain-source voltage of -20 V, continuous drain current of -0.66 A, and on-resistance of 0.52 Ω at VGS=-4.5V. Both channels operate with low logic level gate drive and support an operating junction temperature range from -55°C to +150°C.

Feature Summary

• Dual configuration integrating N-channel and P-channel MOSFETs within a single compact surface-mount package.
• Operates effectively at low logic level gate drive voltages for efficient control.
• Epoxy material meets UL 94 V-0 flammability rating standards.
• Halogen-free construction designated as a green device.

Applications

• Low-side and high-side switching circuits
• Power management applications requiring complementary channel pairs
• Battery protection modules

Procurement Notes

Verify the specific ordering suffix when purchasing. The standard -TP suffix indicates RoHS compliance. An alternative -TPA suffix exists which utilizes a different tape and reel pitch (2mm versus 4mm). Confirm the required packaging specification matches the design requirements before procurement to ensure compatibility with automated assembly equipment.

Selection Notes

Select this component for designs requiring a matched N/P pair in a minimal footprint. Ensure the application current remains within the 0.75 A and -0.66 A limits. Verify that the gate drive voltage aligns with the low logic level operation characteristics. Consider the thermal resistance of 833 °C/W when designing the PCB copper area for adequate heat dissipation.

Part Context

This part belongs to Micro Commercial Components' dual MOSFET portfolio. It consolidates two discrete transistors into one SOT-563 housing. This integration reduces board space compared to using separate single-channel devices. The component serves as a direct replacement for other dual MOSFETs in similar packages where matching electrical characteristics are required.

Replacement Considerations

Check pinout compatibility when substituting. Verify that the replacement device supports the same 20 V breakdown voltage and comparable on-resistance values. Ensure the new component also offers low logic level drive capability if used in existing low-voltage control circuits.

FAQ

What is the difference between the SIX3439K-TP and SIX3439K-TPA?

The primary difference is the tape and reel pitch. The -TP version uses a 4mm pitch, while the -TPA version uses a 2mm pitch.

Does the SIX3439K-TP contain halogens?

No, the device is halogen-free and classified as a green product containing less than 900ppm bromine and chlorine combined.

What is the maximum operating junction temperature?

The maximum operating junction temperature is +150°C.
